8 MAINTENANCE & LUBRICATION
8.8 AIR CLEANER ________________________________________________________
To clean the air filter when the filter service indicator shows
red
Clean the Vacuator Valve
If, your air cleaner has a Vacuator Valve visually check and
physically squeeze it. Make sure the valve is flexible and
not inverted, damaged or plugged. If it is damaged, it will
need to be replaced.
Remove the Primary filter
Unlatch the service cover. The cover is twisted to the left to
remove from the filter housing. The radial seal filter fits
tightly over the outlet tube. There will be some initial
resistance, the same as breaking the seal on a jar. Carefully move the end of the filter backwards and forwards to
break the seal then rotate while pulling straight out. Avoid knocking the filter against the housing.
Inspect the Old Filter
Inspect the old filter for any signs of leaks. A streak of dust on the clean side of the filter is a telltale sign.
Eliminate any source of air leaks before installing the new primary filter.
Inspect the New Filter
Inspect the new filter for any damage that may have occurred through mishandling. NEVER install a damaged
filter. Visually check the inside of the open end, which is the sealing area. Do not wipe the filter radial seal sealing
area. Donaldson radial seal filters have a invisible dry lubricant on the seal to aid installation.
Insert the New Filter
Insert new filters carefully. Seat the primary filter by hand, making certain it is inserted completely into the air
cleaner housing. To complete a tight seal, apply pressure by hand at the outer rim of the filter, not the flexible
center. No cover pressure is required to hold the seal in place and one should NEVER use the service cover to
apply pressure. This could damage the housing and fasteners and void the warranty. If the service cover presses
against the filter before the cover is fully in place, remove the cover. With cover off, push the filter further into the
air cleaner by hand and then the cover will go on with no extra force. Once the filter is in place, secure the service
cover.
Check Connectors for Tight Fit
Make sure service indicators are reset and in proper working order. Check that all mounting bands, clamps, bolts,
and connections in the entire air cleaner system are tight. Check for holes in piping, and repair or replace as
needed. Any leaks in the intake piping will admit dust directly to the engine. Reset the filter service indicator.
NOTE: Extensive damage to engine can result from an inadequate air supply.
